PHOTOGRAPHIG-PRIN '1' WASHER.

Specification of Letters Patent.

Patented Aug. 13, 1918.

Application filed J'une 28, 1917. Serial No. 177,578.

To all whom it may concern:

Be it known that I, Lnwrs B. HALL, a resident of Pittsburgh, in thecounty of Allegheny and State of Pennsylvania, have inoutward along thebottom of a retaining pan,-

and inward at the surface of the water contained therein. Other objectsof the invention will be more fully set forth in the followingspecification.

Referring to the drawings, Figure 1 is a partial diagram and centralvertical section through a container suitable for use with my device;Fig. 2 is an enlarged side elevation of a nozzle; Fig. 3 is a centralvertical section through the nozzle; and Fig. 4 is a horizontal sectionon the line H of Fig. 2.

The invention comprises an open-topped receptacle adapted to containwater, of a depth of several inches, preferably of circu lar form andwith a flat bottom. In combination with such a retaining vessel 1 anozzle is provided, adapted to seat on the bottom of the vessel at ornear its central point, and having a plurality of lateral openings 6near the bottom of the vessel. Through this nozzle water under pressureis injected, and flows outward from the nozzle along the bottom of theretaining vessel. This will produce a current running outward from thecenter of the pan, up along the side walls, and inward on the surfacefrom the upper edge toward the center.

Photographic prints, which in course of preparation must be washed for aconsiderable time in fresh water, when placed in a pan provided with thenozzle herein described will be constantly in contact with the currentof fresh water set up by the apparatus described, and since there is acurrent at the top flowing inwardly, the prints will tend to stay in thepan, following the current of water rather than to wash over the edgethereof, and so may be left in such a pan without the need of furtherattention for an indefinite time, with the certainty of being constantlywashed by fresh water, and without danger of sticking together or beingwashed over the edge.

My invention comprises a conical shaped nozzle 2 having an enlarged flatbottom 3, a

raised bead or flange 4 about the smaller end, which terminates in acylindrical portion 5. This flange and cylindrical portion are adaptedto engage the end of a rubber hose, through which water is supplied tothe nozzle. Near the base of the nozzle and just above the inner bottomwall, a series of horizontally alined perforations are provided, equallyspaced about the nozzle.

The inside of the nozzle is an enlarged chamber as shown in Fig. 4:, andthe base is somewhat thickened in order to make the nozzle more stablein position.

This form of nozzle is adapted to be used with any convenient container.By its use, the necessity for a special kind is obviated.

I claim 1. In apparatus for washing photographic prints, the combinationwith an open container, of a flat bottomed conical shaped nozzle, havingan annular 'rib about its smaller end adapted to engage a hose andhaving a closed base at the larger end, with a plurality of lateralalined openings near the base.

2. Apparatus for washing photographic larger end forming a base adaptedto seat on' a flat surface, and having a plurality of lateral openingsuniformly spaced apart around and near the base.

In testimony whereof I have hereunto set my hand.
